2nd degree burn on laser tattoo removal. Popping the blister

Tattoo Removal

It is said that during laser tattoo removal that you will suffer from blisters. Doctors say to extract the liquid as a sterile as possible using a syringe but I didn't have one so I was still sterile and using a number 11 scalpel iodine and a surgical tray kit.
Huge blister on my right hand 2 days after my second laser tattoo removal session.
